Not my report, but I am seeing the same issue.
Steps to reproduce:
Put a copy of the site on Pantheon. Their varnish config removes the cookie. Cf. https://docs.pantheon.io/caching-advanced-topics#cookie-handlingPossible solution: use JS cookie detection, as eu_cookie_compliance optionally does. Or allow users to change the cookie name so they can chose a name which can bypass Pantheon's Varnish config.

Pantheon's response headers delete the popup_message_displayed cookie.
This can be fixed by changing cookie name to STYXKEY_popup_message_displayed.
